We received a beautiful gift at our wedding this weekend that either did not have a card or the card got lost in between the hotel room and the car. Although, my mom does not remember seeing a card attached to that gift. Anyway, it is not so easy for me to figure out who gave it to us because it is a duplicate gift from our myregistry.com registry. According to our registries, we still have a few more gifts coming in. This may help with the process of elimination, but how do I tactfully reach out to people who didn't give us gifts to ask who may have given it to us? I want to be sure that this person gets a thank you note!
